Abstract: 1,218,579. Rotary-piston I.C. engines. VISH MASHINNO-ELEKTROTECHNITCHESKI INSTITUT. March 12, 1968 [March 13, 1967], No. 12092/68. Heading F1F. A trochoidal-type engine has a two-lobed piston 10 fixed to a hollow rotary-shaft 7 and lodged in a three-lobed cavity within a housing 32, which (when the piston revolves) gyrates orbitally about the shaft axis under the control of two sets of gears 21 meshing with respective gears 6 attached to the shaft. Journals 23 on the housing engage with eccentric bushes in the gears 21, which are carried by bearings 18, 19 secured to a corresponding gearhousing 30. Ports 11, 12 for fuel-air mixture and exhaust gases, respectively, are formed in the piston and connected through the shaft to a carburretter 17 and an exhaust-gas turbine 4. The piston is cooled by air drawn through ducts 8, 8a by a blower 5. A spark-plug 33 is provided in each lobe of the cavity. When the engine is modified to operate as a Diesel engine a fuel injection nozzle is lodged in the piston, Fig. 14 (not shown). Radial seals 38 between the lobes of the cavity engage with the periphery of the piston and are interconnected by axial seals 46 abutting the ends of the piston. The seals and modifications thereof, are described in detail with reference to Figs. 8 to 13 (not shown). A fan 13 driven by the shaft 7 blows air across cooling fins 34, 35. Lubricating oil for the bearings, gears and seals is stored in the housings 30 and pumped through channels 59, 22, 24, 25 associated with each of the gears 21.

Title: Spark machining apparatus
IPC: B23H1/00
Filed: 1957-04-15
Abstract: 828,561. Cutting by spark erosion. FIRTH STERLING Inc. April 15, 1957 [April 20, 1956; March 11, 1957], No. 12213/57. Class 83(4). Apparatus for machining a workpiece W by spark discharges in a dielectric medium between the workpiece and an electrode 26, has capacitive storage means 70 charged by a unidirectional periodic voltage and discharged through the spark gap G by means 80 which periodically render the discharge circuit conductive in timed relation to the periodic charging voltage. The charging current for the capacitive means 70, which comprise a pair of large-capacity condensers 70a, 70b in parallel, is derived from a three-phase supply 78 through transformer 77, full-wave rectifier 75 and inductor 76 in resonance with the supply. The discharge circuit includes an ignitron 80 which is triggered by a positive pulse applied to its igniter from a keying network comprising transformer 90 fed from the supply 78, tapped inductor 92, condensers 94, 99, saturable inductors 96, 98, resistance 102 and rectifier bridge 100. A saturable reactor 72A precludes reverse ignition conduction which may occur due to induced voltage. The capacitor 70 provides large energy spark discharges at a low repetition rate. A small capacitor 110 in parallel with the capacitor 70 may be used alternatively to provide low energy discharges at a high repetition rate. Capacitor 110 is charged from capacitor 70 and its discharge circuit includes half-wave germanium rectifiers to eliminate the negative current halfcycles. The electrode 26 may be a disc coated with a semi-solid dielectric such as petroleum wax, as described in Specification 791,984, and driven by a non-synchronous motor 40 fed from the supply 78 which is controlled by a main switch 120 and a contactor switch 125b closed by a relay 125 in circuit with a starter button 126. The disc is preferably for dressing a tool W, Fig. 2 (not shown). A selector switch 130 is used for selecting the large energy discharges used during roughing down, by closing contacts 135a, 135b, 140a; for selecting the low energy discharges used during finishing, by opening contact 140a, which shuts off the keying network and hence renders the ignition 80 non- conductive, and opening contacts 140b; or for stopping the discharges. The apparatus has an adjustable non-magnetic work-holder 25, Fig. 1 (not shown). In another embodiment, Fig. 11 (not shown), the electrode is used for drilling a workpiece and a non-inductive liquid cooled resistor is connected across the gap and absorbs the negative pulses. In a further embodiment, Fig. 12, a pair of capacitors 170A, 170B are connected in parallel with the spark gap G and are controlled respectively by ignitrons 180A, 180B which are triggered alternately by the keying circuit which includes separate diodes 200A, 200A<SP>1</SP>; 200B, 200B<SP>1</SP> instead of the rectifier bridge 100. Specifications 737,397 and 767.555 also are referred to.

Title: Improvements in or relating to integrating apparatus
IPC: G01D1/04
Filed: 1954-04-30
Abstract: 746,715. Integrating-apparatus. BAILEY METERS & CONTROLS, Ltd. April 30,1954 [April 30, 1953], No. 12587/54. Class 106 (4). [Also in Group XVIII] Integrating apparatus of the kind comprising an escapement 43 and co-operating pawl 11 adapted to control periodic starting and stopping of a driven shaft 45 for actuating a register 46 at constant speed and to determine the durations of the periods of rotation of the shaft, and a cam 42 arranged to act in conjunction with measuring means 4 responsive to a variable to be integrated in order to effect engagement of the pawl 11 with the escapement wheel, has the escapement wheel 43 connected with the driven shaft 45 through gearing so arranged that the reaction torque at the escapement wheel resisting a torque tending to rotate the driven shaft, is less than the driven shaft torque. A link 1 rotates an arm 2 to set a shaft 3 in accordance with a variable whose value is indicated as shown at 4 or recorded. A beam 8 is located at one end by a pivot 7 set in accordance with the variable by the shaft 3 through a beam 6, and a roller 9 at the opposite end of the beam 8 is oscillated between limits by the constant speed cam 42 so that a pin 10 on the beam 8 actuates the pawl 11 about its pivot 12 for periodic engagement with the escapement wheel 43 to regulate the actuation of register 46 exhibiting the integrated value of the variable. The cam 42 receives a smooth constant speed drive from a gear-wheel 26 on an output shaft 25 which is driven through a gear train from a turbine impeller 20. To the shaft 25 is attached one end of a regulating spiral spring 34 secured at its outer end to a housing 33 on a hollow shaft 32 on which is a gear-wheel 31 in mesh with a train of gear-wheels ending with an escapement wheel 28 controlled conventionally to impart an intermittent drive at constant average speed. The regulating spring arrangement 31, 32, 33, 34 serves to smooth and regulate the drive from the turbine to the cam 42 and to a spider plate 47 on the same shaft 41, upon which the escapement wheel 43 is rotatable. The plate 47 carries differential gear-wheels 48, 49 meshing respectively with gear-wheel 431 integral with the wheel 43 and gear-wheel 44<SP>1</SP> integral with a gearwheel 44 driving the register 46. A brake 51 frictionally engages the shaft of the gear-wheels 44, 44<SP>1</SP> and prevents actuation of the register 46 while the pawl 11 is disengaged from the wheel 43, the planetary motion of the gear-wheels 48, 49 driving the wheel 43. When the pawl 11 engages the wheel 43, the same planetary motion drives against the action of the brake 51, the gear-wheel 44 to drive the register. The reaction between the wheel 43 and the pawl 11 necessary to prevent rotation of the wheel 43 is small due to the mechanical advantage afforded by the differential gearing. Specification 393,795 is referred to.
